PLOW.

Specification of Letters Patent.

Application filed August 21, 1911.

Patented July so, 1912.

Serial No. 645,061.

To all whom it may concern:

Be it known that I, CHARLES W. I-I1oKs,a citizen of the United States,residing at Sutherland, in the county of Hillsboro and State of Florida,have invented new and useful Improvements in Plows, of which thefollowing is a specification.

This invention relates to improvements in plows, and more particularlyto an attachment or part which combines the features of a bracket orguide for the vertical bar of a subsoil attachment and of a part of theframe of the plow itself. In this connection reference may be had by wayof an ample to my'prior U. S. Patent No. 990,738, of April 25, 1911,wherein there is shown a lower bracket 11 which forms a guide for thebar 6 of the subsoil attachment. In the construction shown in my saidpatent, the bracket 11 is attached to the landside and a special bracketcarried by the mold board is required for the attachment of the handleadjacent the bracket 11. Or, in some cases, depending on the particulartype of plow, the handle also may be attached to the landside. Oneobjection to this arrangement is that the form of the bracket for thesubsoil bar and the attachment to which the handle is fastened must bevaried in accordance with the type of plow to which the subsoilattachment is to be applied, thus adding to the expense of production.

One object of the present invention is to provide an attachment of thecharacter re ferred to which may be interchangeably applied, without anyvariation, to plows of different types, including both those with ironbeams and the less frequently used constructions which have woodenbeams.

The improved attachment has the further advantage of causing all thestresses incidentto the use of the subsoil attachment to be taken up bythe beam, instead of partly by the beam and partly by the landside orsome other part of the plow, as heretofore.

The improved attachment has the further advantage of being intrinsicallyless expensive than the constructions which it is deaccompanyingdrawings,

tional view on the line 22 of Fig. l; and Fig. 3 is a perspective viewof the attachment which forms the subject of the present invention. 7

Similar characters of reference designate corresponding parts throughoutthe several views.

In order that the application of the present improvement may be morereadily understood, a brief and general enumeration of the essentialparts of a plow and subsoil attachment, such as is shown in my priorpatent referred to, will be given. These parts are the beam 1; the point2; the mold board 3; the landside 4c; the frog 5, which carries thelandside, mold board, and point; the handles 6 and 7; the subsoil blade8; the bar 9, which carries the subsoil blade; and the upper bracket 10for said bar.

The attachment which forms the subject of the present invention is shownin detail in Figs. 2 and 3, and is designated generally by the numeral11. The attachment 11 is preferably in the form of a casting, althoughits various parts may, if desired, be constructed separately and rigidlyconnected together. The attachment 11 includes a bracket 12, which hasat its rear end a slot 13, and which serves as the lower guide for thebar 9. The bracket 12 projects rearwardly from a forwardly anddownwardly inclined flange 14., which projects laterally from a bodypart 15. The outer edge of the flange 14 inclines downwardly andinwardly toward the landside, thereby giving said flange the form of atriangle, and at its lowerend joins with the outer edge of a narrowflange 16, which projects laterally from the lower edge of the part 15and extends to the forward end of said part. The body part 15 includesan attachment member 17 and a bracket member 18. The attachment member17 is formed for association with the lower rear end of the beam 1, andhas on that face which is adjacent the landside a comparatively wide rib19, v

which fits between the flanges of said beam. Through said member 17 areformed the openings 20 to accommodate the bolt and nut fastenings 21,which bind together the frog, the beam, and the attachment 11. It may benoted that the fastenings 21 are the same fastenings which'a-reordinarily used to connect the beam and the frog, and that the.arrangement of the openings 20 is selected; with regard to thearrangement of these fastenings. The bracket memberlS nation of thebracket member 18, and, of

course, of the flange 14:, is selected with regard to the inclinationwhich may be desired for the handle 7 For the purposes of strength andrigidity, the member 18 is connected to the flange 14, along thejunction of the latter and the bracket 12 by a transverse web 25, whichis in a plane perpendicular to said flange. The rib 19 corresponds inoutline to the lower rear end of the beam 1, and in fitting theattachment to a plow, said rib is fitted conformably between the flangesat the lower rear end of the beam 1 and the attachment is secured by thebolt fastenings 21, as above explained. The rib 19 thus serves as ameans for insuring the centering of the attachment, as well as a meansfor maintaining a rigid association of the attachment and the beam.Thereafter, the attachment and the handle 7 are connected by the bolts23 in the manner explained, and the bar 9 is inserted through the slot13. The flanged lower end of the member 17 rests and has a bearing uponthe usual blade which is formed at the lower end 1 of the frog 5, andthe relation of these parts is a further factor in insuring the rigidityof the connection between the attachment and the beam.

It will be apparent from the foregoing '7 description that theattachment 11 causes all of the stress of the subsoil adjunct to beplaced upon the lower portion of the beam, which lower portion is amplysufficient to take up and resist all stresses that may be 7 developed.Furthermore, in view of the may be formed as a casting, it will beobvious that it may be produced at a compara-- tively low cost.

I claim as my invention:

1. As an article of manufacture, an attachment for subsoil plows havinga bracket at its rear end which serves as a guide for the subsoil barand a part in advance of said bracket for attachment to the beam of theplow, the attachment part having its inner face provided with a ribwhich fits conformably between the flanges of the beam at the lower rearend of the latter.

2. As an article of manufacture, an attachment for subsoil plows havinga bracket at its rear end which serves as a guide for the subsoil barand occupies a horizontal plane, a part in advance of said bracket whichincludes a vertical member for attachment to the lower rear end of thebeam of the plow and a vertical bracket member in the plane of thefirst-named member and located between the latter and said bracket andtowhich one of the handles of the plow may be fitted, a flangeconnecting the bracket member and the bracket, and a web connecting thebracket member and the flange.

3. As an article of manufacture, an attachment for subsoil plows havinga bracket at the rear end thereof which serves as a guide for thesubsoil bar of the plow, a part in advance of said bracket forattachment to the beam of the plow, and a second part intermediate saidbracket and the first-named part having a pair of spaced parallel sideflanges between which the lower end of one of the handles of the plowmay be fitted.

4. As an article of manufacture, an attachment for subsoil plows havinga bracket at the rear end thereof which serves as a guide for thesubsoil bar of the plow, a part in advance of said bracket forattachment to the beam of the plow, said part being provided upon itslandside face with a rib adapted to fit between the flanges of the beam,and a second part intermediate said bracket and the first-named part forattachment to one of the handles of the plow.

5. As an article of manufacture, an attaclnnent for subsoil plows havinga bracket at the rear end thereof which serves as a guide for thesubsoil bar of the plow, a part in advance of said bracket forattachment to the beam of the plow, said part being provided upon itslandside face with a rib adapted to fit between the flanges of the beam,and a second part intermediate said bracket and the first-named parthaving a pair of spaced parallel side flanges between which the lowerend of one of the handles of the plow may be fitted.

In testimony whereof I have hereunto set my hand in presence of twosubscribingwitnesses.
